Yes, I recompiled with just WITH_ACPI, and now it's 1 as default.
I even cvsupped world and rebuilt, and now nvidia.ko doesn't try the
agp0 stuff. I guess that's progress, but AGP still doesn't work.

What would the NvAGP "3" option do, then, if it couldn't fall back on
nvidia's agp implementation? I supposed it could do both if you built
with WITH_FREEBSD_AGP. Oh well, it's gone now.
